THIS IS SO GOOD! OMG AMAZING AMAZING! The cast is perfect and the acting is just superb. I love Joo Won even more now. He is just so good at acting it leaves me speechless. This is unlike any other kdrama but it will break your heart with all the bullying and evil plotting. I seriously want to punch somebody when people do mean thing to Si On (Joo Won). Moon Chae Won is also amazing as always. They make a perfect couple and I will ship this to the end.
